/* dD Tech: zajednicki izgled svih stranica (redizajn 26.10.2026., smjer B "industrijski grafit").
 * Svijetla stranica, grafitni pojas (izbornik, uvod, podnozje), zlato kao gumb i naglasak.
 * Jedini izvor palete i fonta: stranice u svom <style> drze samo raspored vlastitih komponenti i boje uzimaju iz tokena.
 * Pokriva podskup Bootstrap 5 klasa koje stranice koriste (mreza, razmaci, gumbi, kartice, forme, izbornik, accordion),
 * pa Bootstrap vise ne ucitavamo. Ponasanje (izbornik, padajuci jezik, accordion, tema) je u js/ui.js.
 * Kontrast (WCAG): tekst #111827 na #F5F6F7 16:1, sporedni #4B5563 7:1, link #8C641C 4,9:1, zlato na grafitu 6,3:1. */
